T at whom, it -m ctyco-ncern:

Be it'known-that I, J 0st GONZALEZ 'BABIQ,

a subject .of the King of Spain, residing at; New York, in thecounty of New York and{ State of New York, ?have invented certain;

new and useful Improvements in Friction- Clutches, of which-the-followingis a specifii appertains to make and use This invention relates to friction-clutches i forusein transmittingthe-motion of a driving. or main power shaft to a driven or powertransmitting shaft; and the objectthereof is to provide an improved device-of this class, 3 which I call a double" "friction-clutch and I inwhich'thefriction-surfaceiscomp aratively large, my improved clutch beingalso' more powerful than other devices of this class as usually constructed and being also lighter than ordinary friction-clutches and occupy- ;ing lessspace on ashaft, a further advantage being'in'thefact that the friction parts can bereadily removedin making repairs without removing the driving and driven pieces from the shaft or shafts.

Another object ofthe invention isto provide-at-friction-clutch of the class specified wherein the clutch devices arenot affected bycentrifugal motion oraction and'in which the said clutch devicesare under automatic control and with these and" other obj ects in view' theinventionconsists-in a clutch device by suit-able reference characters the views, and in which ofthe class specified constructed as *herein after described and claimed. 1

The invention is-fullydisclosed inthe following specification, of which the accomp anying drawings-form apart, in which the-separateparts of my; improvement are designated in each of t *Figure 1 is arear-end view of thatpart of my improved clutch. which in practice is mounted ori the mainpower or-driving-shaft and showing the means for operating the cone-member,-p art of the construction of the latter beingin sectiony'FigQ 2, a-partial sec- -tion-on the line 2; 2 of-Fig. 1; Fig. 8, asection on the line3=3 ofFig. 2; Fig. 4,a sectionon the line4 4 of Fig. 2 ;Fig.- 5, anenlarged back or outerview of the cone member and showing the-main power or driving shaft in section; Fig.6, atransverse section of a-hub member which in practice is rigidly se f cured tothe-main-power or driving shaft and whieh forms apart of the clntchmechanismi connected with said shaft; Fig. "7, a trans-- -verse section'of one-of the movable friction members; Fig. 8, a similar view of the other movable friction member; Fig. 9, a -transverse section of the cone member, and Fig. 1 0

In the drawings forming part of this. s'pecifi' cation-I have shown-at as a main power or driving shaft and at 00 a driven .or fpower= transmitting shaft, andin thepracticeof my invention Imount onand secure to the end of the shaft 01; a-driving-hub a, the rear end portion of which is preferably tapered, vas shown in Figs. Za'nd 6, andsaidfhubisproyided With radially-arranged pairsof arms a vex disk member 0, the concave side of whichisdirected toward the member 6 andthe 'parts'b? and cform acasingd, in-which the operative parts of the clutch are mounted,

and the part c'of the casing d is divided. diametrically-toform two similar parts 0 which 'areboltedtogether, as shown at c in Fig. -1, andthe part c of the casing dis securedto-the part 5 0f said casingby screws orbolts, as shown at c, andthe parts of saidcasingis alsoprovided at its perimeter brat itsjuncture with the part?) with an inwardlydirected annular clutch memberc which 'for the purpose of this description will-be calleda main clutch member or casing clutch member, andthe clutch-member c -forms, as will be understood, apart ofthe casing d and is movable with. said casing'inthe operation of the clutch, ashereinafter described.

The part c of the casing d is provided centrally with an opening a, and mounted on the shaft and movable longitudinally thereof is a collar e, comprising a main cylindrical part 6 having a reduced portion 6 and the 'main cylindrical part is provided with a front face member 6 and .a rear-face mem-- ber eithrou'gh whichtheshaft :v passes, and

Ioo

said main cylindrical part is also provided-in 7i its outer surface with an annular groove 6, in which is mounted a ring or band f, with which is connected a yoke f mounted on an upright support f and pivotally connected with the yoke f 2 at f 4 and with the support f at f is an arm f, by which the yoke f may be manipulated so as to move the cone member 6 longitudinally of the shaft 00.

The collar 6, which is shown detached and in section in Fig. 9 and also in section in Fig.

2, is provided on the front or face thereof with a plurality of pairs of arms e which eX- tend in the direction of the hub a and the ends of which project into the spaces between the pairs of arms a on said hub, and pivoted between the ends of the pairs of the arms 6 as shown at a are levers g, the shorter arms of which project in the direc .tion of the part b of the casing d and are provided with toggle-links g, which are pivoted thereto and also to toggle-levers 9 which are triangular in form, and the toggle-levers g are pivoted at g to the fingers a of the arms a of the hub a.

' Mounted in the recesses 01, of the arms a of the hub a and on the side of the annular friction member 0 of the casing d adjacent to the driven shaft 00 is an annular supplemental friction member h, movable toward and from the annular friction member 0 and the annular friction member h is provided on the side thereof adjacent to the hub b with a :plurality of pairs of ears 71/ as shown in Fig.

7, having pivot holes or openings h in which are secured pivot-pins, and the toggle-levers 9 are provided at their outer corners with oblong slots or openings 9 through which said pivot-pins are passed, and this method of connecting the togglelevers g and the annular friction member it permits of the operation of the said parts, as hereinafter described.

Mounted on the side of the annular friction member 0 of the casing d opposite the annular friction member h and adjacent to the collar e and resting in the recesses a of the arms a of the hub a is another annular supplemental friction clutch member i, movable toward and from the friction member a and provided with ears i which range in the direction of the hub b and shaft 00 inwardly of the friction member 0 and to which the inner corners of the toggle-levers g are pivoted, as

: shown at i in Fig. 2, and the ears i are provided with pivot-pins at i, by means of which this connection is made and which permits of the operation of the toggle-levers g, as hereinafter described.

Secured to the reduced portion 6 of the collar e, as shown in Figs. 2 and 3, is a spiral spring 70, one end of which is also secured to a rin member n, which incloses said spring it an the reduced portion 6 of the collar 6, and the ring member n is provided in its face or perimeter with a deep annular groove W, the

side Walls of which are provided. with notches or recesses a which are arranged substantially tangentially of the walls of the groove n as shown in Fig. 5, so as to form teeth or projections n all of which project in the same direction.

Both the inner and outer faces or the front and back faces of the collar 0 are provided with openings m, through which the ends of the levers 9 project, and adjacent to these openings, as shown in Fig. 5, are mounted pulleys or sheaves m and connected with the outer or rear ends of the levers g, as shown at at m*, are chains or other flexible devices m, which are passed inwardly, radially, and around the pulleys or sheaves m and into the groove n in the ring or band n, which incloses the spiral spring 7c and to which said spiral spring is secured, and the free ends of the chains m are provided with heads m having T-heads m, which are adapted to engage the teeth or projections 17; on the ring member at at the opposite sides of the groove a. As thus constructed it will be seen that the spring is operates at all times to turn the ring a in one direction, that direction in the'form of construction shown being to the right, and this results in pulling the chains or other devices m also to the right, and the rear ends of the levers g are drawn inwardly, and this operation of the chains m may be regulated at all times. If it is desired to increase the pull of said. chains on the levers g, the T-heads m are detached from the ring member a and said. ring member is turned to the left by means of a suitable wrench or other device which. is adapted to engage pins or holes n secured to or formed in said ring, and when the required tension is thus applied to the spring 7c the T- heads m are again connected with the ring member it; but if it is desired to decrease the tension of the spring 7c, the inwardly-directed pull of said spring, and of the chains m" on the levers g, the above-described operation is reversed or the T-heads m of the chains m" are disconnected from the ring member 11, and said ring member is allowed to turn to the right until the tension of the spring 7c is decreased.

The operation of my improved clutch will be readily understood from the foregoing de scription when taken in connection with the accompanying drawings and. the following statement thereof. As shown in Fig. 2, the parts are not in their operative position, and the motion or movement of the shaft :1: will not be transmitted to the shaft x when the said shaft 00 is turned. If it is desired to throw the clutch into operation, the leverarm f 6 is moved in the direction of the arrow 1 in Fig. 2 and the collar 0 is moved forwardly. This operation of the cone member is transmitted through the levers g, togglelinks 9 and toggle-levers g to the movable ITO g to the position shownin'sa'id figure.

It will be observed that the spring k forms ,a tension control for the levers g, and-the :pressureof the friction members hand 2' on; the friction member willbe largely :re u- :latedat all times by the'tension of the sprin'gj 7r, and the tension of said spring may be regu-;

lated, as hereinafter described, by turning the ringmem'berm in the desired direction after the chains 711; have been disconnected therefrom and then resecuringsaidrchains to said ringmember, all as hereinb'efore-described.'

It will be understood that my improved 7 clutch or the operative parts thereof are not influenced in any way by centrifugal force,

, and by employing a number of the levers g,

which are connected with the spring-operated ring member n at difierent points, the energy of the spring is is subdivided and the operation of the said parts ,on the friction members h and 'i is thus equalized and the separate parts of the clutch are equally balanced. By making the clutch-casing member 0 detachable and making said member of separate parts all the operative parts of the clutch are rendered easily accessible for cleaning, repairing, and other purposes, and

the driving parts of the clutch may be. substituted by new ones whenever desired. It will also be understood that in practice the casing d is provided with a quantity of oil or partially filled with oil and the rotatable parts, including the parts it and t of the clutch which are movable toward and from the clutch member 0 are all turned in oil and the overheating of the parts is thus avoided. Another feature of this clutch is that the operative parts thereof within the casing 01 are all protected from dust and dirt of various kindsand classes, and the levers 9 being under a tension control it will be apparent that the starting and stopping of the shaft may be eflected gradually without the jerking, jolting, or jarring which usually accompanies the operation of clutches of this class as usually constructed.
